If you are trying to vape and the battery seem to be working but no vapor is coming out of the cartridge, try unscrewing the cartridge from the magnetic connector and screwing in back on again (to ensure that there is a contact between the connector and cartridge).

Make sure the connecting surfaces on both the vaporizer chamber and cartridge are clean and free from debris. (There needs to be a solid connection between the metal part of the cartridge and metal part in the battery chamber so they can conduct an electrical charge).

If the problem persists it means that you are not getting a connection between vaporizer and cartridge or it could either be a faulty cartridge or there is a problem with your vaporizer battery (faulty vaporizer).

Always make sure your Leaf Buddi UI vaporizer is charged and turned ON. If you are pressing the top operation button and nothing is happening, please make sure the device is turned ON by pressing the button 5 rapidly. If the LED button starts blinking 5 or more times, when you are trying to use the device, this means that the battery is out of power and needs to be recharged. ...
